I absolutely love the style of these simple line drawings - especially the one in the upper right that's a pair of guy's underpants. Funny! And how great is the chalkboard instead of a mirror? Not that practical, of course (unless the opposite wall is mirrored), but awfully cute.
One quick note: when framing these paintings (and the photos and other paintings in pictures below), it's really important to do a good job. The humidity in a bathroom can ruin art, and nobody wants that to happen. It even makes sense to rotate the art out occasionally.
